The news of OpenOffice.org's third major release has generated quite a bit of buzz on the internet for many reasons, one of which being that it now runs natively on a Mac (sans X11). ZDnet has posted a screenshot gallery of OpenOffice.org 3.0 for those who have yet to try the hot-off-the-press application.

The answer to the how you ask is that there arn't enough contributors for Mac PPC. OOo isn't a large company that can just employ a PPC engineer just like that. If nobody is volunteering their time to Mac PPC, then there is no Mac PPC release. Simple.
